I cant figure out how to mod the steam version. IK how to install the normal KSP mods but I have no clue on how to install KSP mods for the steam version.

i am having the same problem

you should be able to open the steam common folder this is an file directory example (C:\Program Files (x86)\Steam\steamapps\common\Kerbal Space Program) then mod like you would normally. A steam workshop would just make it more convenient not having to rout around in steam’s files.
